WALL CONSTRUCTION.

Application filed March 24, 1921.

T all whom it may concern:

Be it known that l, EDWARD R. BRAINERD, a citizen of the l mited States.residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in FallConstructions, of which the following is a specification.

It is the object of this invention to prom vide means for interlockingthe parts of' a. building construction, such as the walls thereof.

The improved interlocking connection may be employed between theportions of studs supporting wall panels, or between the panels of awall, where the latter is enlarged to provide auxiliary studding, or theimproved interlocking joints may be arranged between the varioussuperimposed members forming the panels of walls.

lhe invention will be readily understood from the following descriptionof the accompanying drawings, in which- Figure 1 is a perspective Viewof a wall employing the improved interlocking joints.

Fig. 2 is a vertical section through one of the studs of the wall.

Fig. 3 is a plan View showing the method of turning a corner of thewall.

Fig. l is a perspective view of one of the building blocks employed forwall construction and having the improved interlocking means.

Fig. 5 is a similar view of one of the members forming the panels of thewall construction and provided with the improved interlocking meanswhereby superimposed members are connected.

in the drawings 1 have illustrated a wall at construction includingfoundation members 1 having studs 2 extending upwardly therefrom withspaced wall panels 3 between adjacent studs. 5

The studs comprise blocks built up upon one another and arranged inseries provided with co-operating interlocking means adapted to receivea plastic binding material in order to form rigid structures of thestuds. The studs may be formed of blocks, such as shown in Fig. 4, andincluding a surface 4 adapted to have members 3 forming the respectivepanels of a hollow wall structure connected thereto, as by providinggrooves 5 at the edges of surface 4 Serial No. 455,003.

receiving co-operating ends 6 of members 3 in said grooves.

The co-operating grooves and ends received in the same, preferablyinclude surfaces 7 perpendicularly disposed with rela tlon to surface4:, and surfaces 8 extending therefrom and angularly disposed with relatlon to surface 4. By this arrangement the panels of the side walls maybe readilv connected to the blocks forming the studs and W111 be rigidlyheld with relation to said stud blocks.

As previously stated, the stud blocks are arranged one upon another withthe side walls extending from surfaces 4 of the stud blocks, and twoseries of the stud blocks are arranged along side of one another. inorder that the side walls extend in opposite directions from the studsthus formed. The two series of stud blocks are connected by the improvedinterlocking means and are also secured to the foundation members 1 bymeans of the plastic binding material formmg a part of the interlockingconnection.

As an lnstance of this arrangement the surface of a stud block oppositesurface 4 is provided with a recess 10 which is formed with undercutside edges 11 extending from said surface of the block. lhe recess ispreferably formed as a dovetail recess, as clearly shown in Fig. 4. Whenthe two series of stud blocks are positioned adjacent one another, therecesses 10 co-operate to form an opening extending vertically throughthe stud as thus formed, and said opening is adapted to receive asuitable plastic binding material as shown at 13. This plastic binderpreferably extends downwardly below the stud blocks into a suitablerecess 14 rovided in the foundation block 1 upon which the stud issupported. Suitable reinforcing elements 15 may be embedded in theplastic binder in usual manner.

The corner stud for a wall construction may also be formed with theimproved look ing joint. For this purpose instead of forming the twoseries of studs of blocks, such as shown in Fig. 4, I employ blocks suchas shown in Fig. 3. These blocks are arranged in two series alongside ofone another with surfaces 4 of the blocks provided with recesses 5adapted to receive wall pan els 3. The meeting surfaces of the adjacentseries of blocks are arranged at right angles to the surfaces 46 and areprovided with cooperating dovetail recesses 10 in order that a plasticmaterial 13 may be received in the opening formed b said recesses.

The surface 0 the stud thus formed, which is angularly disposed withrelation to surfaces 4, is adapted to have a series of blocks 18received against the same with wall panels 3 extending from said seriesof blocks. For this purpose the blocks 18 are provided upon their outersurface with recesses 5 adapted to engage the wall panels and theadjacent surfaces of the studs and the blocks 18 are provided withco-operating dovetail recesses 10 arranged to receive a plastic binder13 By this arrangement the parts forming a corner stud may beinterlocked by means of the improved locking connection, and wall panelsmay extend angularly from the respective sides of the corner studs.

In forming walls, as thus described, it is sometimes desirable toprovide additional supports in the way of studs between the spacedpanels forming the hollow wall construction and intermediate of thelength of said panels. For this purpose inwardly projecting blockstructures 20 may be provided upon panel members 3 so that the blockmembers upon the respective spaced panels of a wall construction willabut against one another in order to form a stud extending the height ofthe wall between the spaced panels thereof. The adjacent surfaces ofblock members 20 are provided with dovetail recesses 10*, such aspreviously described, and the opening formed by the co-operating recessis adapted to receive the plastic binding material 13, as previouslydescribed.

The superimposed panels 3 forming the respective spaced wall structuresmay also be provided with an interlocking connection. For this purposethe panels 3 may be provided intermediate of their ends with inwardlyextending enlargements 22 having openings through the same arranged astwo of the co-operating dovetail recesses, such as reviously described,and as shown at 10". hese openings preferably extend within enlargements22 only a short distance from the upper and lower edges of the panels 3,

and are thereby so arranged that when the panels are superimposed, theadjacent edges of the panels will form co-operating recesses adapted toreceive the plastic material 13.

It will thus be seen that I have provided an extremely practicalinterlocking means adapted to be employed in building con struction andarranged for use wherever it is desired to rigidly unite variouselements of the structure. Although in the practical embodiment of theinvention illustrated, such an interlocking means has been shown asarranged for several practical uses, it will be understood that thescope of usefulness and the method of using the interlockin joint is notlimited to the present exemp ification of the invention.

Various changes may be made without departing from the spirit of theinvention as claimed.

. What is claimed is:

1. A building block having one surface provided adjacent to its edgeswith substantially V-shaped grooves that are adapted to receive theWedge-shaped ends of wall anels, and there being a dovetail recess ormedin another surface of said block adapted to receive plastic bindinmaterial in order to form an interlocking oint with an adjacent similarblock.

2. A building block having formed in one of its vertical faces adovetailed recess that extends from the top to the bottom of said block,and there being a substantially V- shaped groove formed in another oneof the faces of said block adjacent to one of the corners thereof.

3. A building block provided on one of its vertical faces with acentrally arranged dovetailed recess that extends from the top to thebottom of said block, which recess is adapted to receive plastic bindingmaterial to form an interlocking joint with an adjacent wall block, andthe face of the block opposite to the face that is provided with thedovetailed recess being provided adjacent to its edges with verticallydisposed V-shaped rooves that are adapted to receive the we ge shapedends of wall panels. I

In testimony whereof I have signed my name to this s ecification.
